See this tutorial: Product Key - Change in Windows 10

Superfly is suggesting your machine may have been upgraded previously and already have a digital licence on Microsoft's activation servers. If that is the case, it should activate automatically if you enter the Windows 10 Pro generic product key:

If you upgraded to Windows 10 for free and ended up in a non-activated state, try following these steps:

• Go to Start
  
  , then select Settings > Update & security > Activation.
• Select Go to Store, and check to see if a valid license is available for your device. If a license isn't available, you'll need to buy Windows from the Store.
  
  Note
  • This only applies if you haven't made changes to the hardware for your device.

or you could hack it with a crack but please note this is always risky and you don't know what's in the hack
